Show affiliationsThe general expression for the entropy production in cosmologies with variable effective cosmological 'constant' ( Lambda ) is presented. By assuming that Lambda decays as Lambda = alpha R-m+ beta (R/R)2, where R(t) is the scale factor of the FRW models, the second law of thermodynamics and the Landau-Lifshitz theory for non-equilibrium fluctuations are used to establish constraints on the parameters alpha , beta and m.
